Under the available conditions for advanced Tokamak experiments, studies on some key projects of magnetic fusion science were carried out, important results were obtained, including the first observation of the toroidal symmetry and three dimensional structures of the geodesic acoustic mode zonal flow and the record of 4.93 keV electron temperature. In other fields such as divertor physics, plasma rotation, effects of energetic electrons, particle and energy confinements as well as MHD instabilities, plentiful experimental data were obtained. The modification and upgrading of the device is being in the stage of research & development., authors=null, authorsList=null, authorCompany=null, correspAuthors=null, authorNote=null,

MW，增加了液氮温度分子束加料系统，三台阶带状流探针阵列、微波反射仪和汤姆逊散射等诊断系统等。利用其所具备的条件，在该装置上开展先进托卡马克实验，进行了磁约束聚变科学关键课题的研究；在若干领域，取得了重要物理实验成果，包括首次在托卡马克装置上观测到测地声模带状流的环向对称性和三维结构，创造了电子温度达到5 000万度的国内纪录等；在其他领域，比如偏滤器物理、等离子体旋转、高能电子的作用、粒子和能量约束及磁流体不稳定性等方面，积累了丰富的实验数据。该装置的升级与改造工作正在研发之中。, authors=董家齐,严龙文,段旭如, authorsList=董家齐;严龙文;段旭如, authorCompany=核工业西南物理研究院, correspAuthors=null, authorNote=null,
